On the same website it also gives the pros and cons of an elliptical as well! The website Built Lean, states that the pros of the elliptical is that you won’t get the impact on your joints the way a treadmill will so I assume this would be better if you have joint problems. Another pro is cross training ability which is just means it allows you to work out your upper body along with your lower body. The one pro I do not agree with is the reverse stride the elliptical allows. I have seen athletes use the treadmill to do reverse strides, but again they have to be experienced in this but my point is that is it possible to do after practice. The cons of the elliptical I believe will make you want to run to a treadmill though realizing what is really going on while working out. First, if you go fast enough on the elliptical and want to “cruise it” so to speak, the machine’s momentum will keep moving on its own for awhile before slowing down, and all the person has to do is just let the machine move his or her legs, saying that the machine can do a portion of the workout for you and you will not benefit from it at all. I know I’ve done it before. I will go really fast or with a heavy resistance just so when my legs begin to burn I won’t have to work to hard because the machine will keep moving for some time on its own. But, if you do this on a treadmill, you will simply fly off the treadmill and hurt yourself, so the treadmill pushes you to keep running or jum on the side rails there is no cheating.
After reading this article about Elliptical vs. Treadmill: Which is Better? By Kevin Deeth, CPT on the Built Lean http://www.builtlean.com/ you can see it might not be so much which is better, it has more to do with which one will you receive a more comfortable workout so your joints won’t hurt, and which improves your posture. And if the question was which one will burn more calories the website says that also, on the treadmill running for an hour the runner can burn 700 to 800 calories and the elliptical will range somewhere between 700-750 calories. Both would have to be at high interval training. So that is the bottom line, it is not which machine works better; it is which machine provides the most comfort and what level you push yourself.
